Re: IMF Mail Filter (False Positives)

What about from a particular mail domain. Can i just put their mail servers
in (MX records)

IMF itself does not have any whitelisting capabilities. You can whitelist
sending hosts by adding their IP addresses in Connection Filtering's Global
Accept List and enabling Connection Filtering on the SMTP VS. This allows
mail *from those IP addressed* to bypass Connection Filtering (including RBL
listing) and Content Filtering (IMF).

You're trying to disable IMF *FOR* certain recipient domains in your Org -
the above doesn't do anything in to help you with that.

I thought there was a way to add them in the existing IMF.

It is only IP's?

If your server directly receives inbound internet mail, one workaround
may
be to either create an additional SMTP virtual server (or add another IP
address to existing SMTP VS), and map it to a separate external IP
address
on the firewall. Create (or modify an existing) A record to map the
external
fqdn to that IP address, and point the MX record(s) for those domains to
it.
Disable IMF on the new SMTP VS/IP Address.

Alternatively, look at 3rd-party tools like WinDeveloper IMF Tune.

Actually I would just like to add the Domain. Anything coming to
certain
domains. I have about 50 of them that I would like to by pass wth
filter.

What is the best way to stop certain emails from getting blocked by

the

so
the
custom weight filters is not useful.
